MACHINE FOR MAKING STAPLE-FENCING.

Specification of Letters Patent.

Application filed October 21, 1904:. Serial No. 229,362.

To all whom it may concern.-

Be it known that I, SHERMAN S. WITHING- TON, a citizen of the UnitedStates, residing at Adrian, in the county of Len'awee, State ofMichigan, have invented certain new and usevful Improvements in Machinesfor Making Staple-Fencing; and I do declare the following to be a full,clear, and exact des'cription of the invention, such as will enableothers Skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to thefigures of reference'marked thereon, which form a part of thisspecification.

This invention relates to machines for making wire fencing of the typeknown as staplefencing,v wherein the crossed wires are united at theirjunction by tying-staples; and it consists inthe construction andarrangement of parts hereinafter fully set forth, and pointed outparticularly in the claims.

The object ofthe invention is to produce a machine of thecharacterdescribed wherein the arrangement is such as to support andcarry the reciprocatory cross -beam, upon which are mounted the movableparts of the dies between which the crossed strands of the fencing arejoined by the tying-staples, so that said cross-beam may be actuated tobring the parts of the dies into working relation and to separate themwithout imparting undue shock or vibration to the machine, enabling themachine to be run at a higher rate of speed and increasing 1ts capacityin a corre-' sponding degree.

The above object is attained by the structure illustrated in theaccompanying drawings, in

which- Figure 1 is an elevation of a machine embodying my invention.Fig. 2 is a vertical transverse section as on line- 2 2 of Fig. 1,showing in section the crimping-drums omitted from Fig. 1 and betweenwhich the fabric passes after leaving the dies in which the crossedstrands are joined, also showing in section the roller or drum uponwhich the completed fabric is wound, also omitted from Fig. 3 is avertical transverse section as on line 3 3 of Fig. 1. Fig. 4: is anenlarged detail in vertical section through the rocker-arm and itsbearing-support, as on line 4L 4 of Fig. 3.

said main shaft is a pinion 4, which meshes with the gear-wheel 5 on thestub-shaft 6,

journaled in the frame at one end and sup ported at the other end by thebracket 7.

Also fixed to the shaft 6 is a pinion 8, which meshes with a largegear-wheel 9 upon the end of shaft 10, extending longitudinally of andjournaled in the upper portion of the frame of the machine. By means ofthe train of gears just described, through the medium of which the shaft10 is driven, the speed of said shaft is reduced and sufficient powerfurnished for the purposes required. Fixed to the shaft 10, near eachendthereof, are the eccentrics 11, the straps 12 of which are connectedwith the short eccentric-rods 13, whose lower ends are pivotallyattached at 15 to the opposite ends of the cross-head 16, adapted toreciprocate vertically in the frame and carrying the driving-plungers17, adapted to enter the closed dies to drive the tying-staples aroundthe crossed strands embraced between them, as will be well understood inthe art.

The reciprocatory beam 18, which carries the movable dies 19, as shownin Fig. 2, is supported at its ends in the inclined ways 20 in the sidesof the frame and is actuated through the medium of the toggle-levers 21,

which are pivoted at one end to the ends of lower ends and at theirupper ends are pivoted,

as at 26, to one end of the rocker-arms 27 which are journaled upon thepins 28, supported in the frame and in the brackets 29,

the opposite ends of said arms carrying the antifriction-rollers 30.(More clearly shown in Fig. 3.) Fixed to the main shaft 10 adjacent theeccentrics 11 are the cam-disks 31, which are adapted to roll in contactwith the antifrietion-roller 30 on the rocker-arms 27. The tendency ofthe beam 18 is to slide downwardly in the inclined ways 20, so that theweight of said ,beam is at all times carried on the rocker arms, wherebythe antifriction rollers 30 are maintained in continuous contact withsaid cam disks. When the rotation of the shaft 10 brings the lower sides32 of the cam-disks 31 into engagement with the antifriction-rollers ofthe rocker-arms, as shown by solid lines in Fig. 3, the togglelevers 21would be in a position to allow the beam 18 to slide away from the fixedbeam 33, to which the fixed dies 34 are attached, permitting freedom ofmovement of the fabric upwardly through the machine between said dies.As a further rotation of the shaft 10 causes the high sides 35 of saidcams to ride onto the antifriction-rollers of the rockerarms, said armsare actuated to raise the connectin'g-rods 24 and operate thetoggle-levers to close the dies or bring them together upon the crossedstrands of the fabric, as shown by dotted lines in Fig. 3, in whichposition the dies remain while said cam-disks are traveling the distanceof the concentric portions of their arcs, during which time theoperation of driving the tying-staples is accomplished. When the highsides of said cam-disks pass from engagement with theantifriction-rollers of the rockerarms and the eccentric sides of saiddisks engage said rollers, the beam 18is allowed to again slide awayfrom the beam 33 to open the dies and to permit the passage of thefabric upwardly therethrough, as before described. It will therefore beevident that the beam 18 is at all times carried by the rocker-arms,whose antifrietion-rollers travel in peripheral contact with thecam-disks 31, whereby the reciprocatory movement imparted to the beam 18is made gradual with respect to the termination of movement in onedirection and the inception of movement in the opposite direction,preventing all jerking and jarring incident to the sudden starting andsudden arresting of a heavy body and yet imparting a rapid movement tothe beam between the terminals of its reciprocatory movement, therebyenabling the machine to be run at a comparatively high rate of speed. Itwill also be evident that through the medium of the toggle-levers a veryhigh degree of leverage is attained at the moment the working faces ofthe dies are brought together, owing to the fact that said levers willthen occupy nearly a straight line between their centersa position inwhich said parts are maintained during the time the cam-disks aretraveling with their high sides in engagement 42, which in turn'mesheswith the gear 43 on the shaft of the drum 41. The tying-staples 44 areshown upon the inclines 45 and are adapted to be fed into the dies bythe notched feeding-wheels 46, as shown in Fig. 2, so as to be engagedby the plungers 17 and driven into the closed dies to unite thelongitudinal and the transverse strands, the latter being shown at 47 inFig. 2.

Having thus fully set forth my invention, what I claim as new, anddesire to secure by Letters Patent. is
